The problem with the transfer of number to sip-gateway

Hello.

 There are two server with FreePBX. At first when you call through the gateway, the gateway number comes in the form of a string "СÑ,ÐμпР° нÐμнко Ð~Ð³Ð¾Ñ € ÑŒ". On the second server to the gateway comes to an empty string.
 Both servers are installed recently. On both servers configured sip-trunks and outgoing routes.

 What could be the reason? And her decision.

Sincerely.
Igor Stepanenko.
